A method and/or a machine is for tabbing a free end on a roll of sheet material. Converting a master roll of sheet material to the roll of sheet material and winding a first roll of sheet material onto a spindle at a winding position. Tabbing the free end of the roll of sheet material at a tabbing position. Where a tabber carrying a joiner are both in an initial position away from the first roll of sheet material, moving the tabber to a second position adjacent the roll of sheet material, moving the joiner into an engagement position where the joiner is engaged with the free end of the roll of sheet material. The joiner creates a tab with a combination of mechanical entanglement and heat welding. Returning the tabber and joiner to the initial positions. Doffing the tabbed roll of sheet material. The roll produced by the foregoing.

A method for fabricating a sheet structure from paper and/or paperboard material, which provides a thickness dimension ordinarily associated with corrugated paperboard material. The sheet structure is constructed from a first planar linerboard sheet and a second non-planar linerboard sheet, wherein a plurality of projections are cut and folded from the second linerboard sheet and are adhesively coupled to the first linerboard sheet, such that portions of the projections define a standoff between the first and second linerboard sheets.

A local connection of contact surfaces of top and bottom sheets is formed in a defined connection zone. The zone is polygonal and the top and bottom sheets jointly form within the periphery of this zone a connecting lip with their first side faces located opposite one another cut obliquely through their sheet thickness. These first side faces of the sheets and their adjacent obliquely-oriented second side faces in the zone are complementarily beveled in the form of a conical wall running downwards and inwards, so that in the vicinity of these second neighboring side faces the underside of the bottom sheet protrudes inwards past the top surface of the connecting lip at the location of the top outside edges of its first side faces. A method and an apparatus are arranged to implement the local connection.

A tamper-evident food delivery packaging systems, methods of tamper-evident packaging of food for delivery, and apparatus for tamper-evident food packaging operate to form resilient self-fastening perforations through a packaging. A binding apparatus includes an anvil and a flipper plate. A cutter head includes a profile blade and a slot blade. A pusher is pivotably connected between the profile blade and the slot blade. The cutting apparatus moves in a reciprocal motion relative to the anvil while the flipper plate engages a pusher to pivot the pusher during the reciprocal motion.

A fitment including a first layer and a second layer suitable for securing to each other via a mechanical engagement feature, wherein the mechanical engagement feature aligns the first layer and the second layer relative to each other when the layers are engaged and the fitment is folded such that the layers are in contact and at least one of the layers at least partially encloses the other layer.

An apparatus for production of a two-ply paperboard panel is provided. The apparatus comprises a supply of top paperboard panel web. A flap-cutting die cut module receives the top paperboard panel web and cuts a pattern of flaps therein. A flap-forming die roll in juxtaposition with a flap-receiving pocket roll defines an interface therebetween through which the top paperboard panel web is received. An adhesive-application station applies adhesive to surfaces of flaps formed on the top paperboard panel web. A supply of bottom paperboard panel web is provided, which is joined to the top paperboard panel web at a web-merging station. A hold-down system holds the top and bottom paperboard panel webs together while applied adhesive sets or cures. A method for producing a two-ply paperboard panel is also disclosed.
